javascript - How do I grab part of a URL string and make it display as text in the HTML? -


say have url "www.example.com/example.html?storeid=1400&shopperid=1200" , want pull information shopperid equals, in example 1200.i added script header added html. why not working?

js:

function getparameterbyname(name) {     name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");     var regex = new regexp("[\\?&]" + name + "=([^&#]*)"),         results = regex.exec(location.search);     return results === null ? "" : decodeuricomponent(results[1].replace(/\+/g, " ")); }  var shopperid = getparameterbyname('shopperid');

your url isn't formatted correctly. have 2 ?, second should &.

"www.example.com/example.html?storeid=1400?shopperid=1200"

to:

"www.example.com/example.html?storeid=1400&shopperid=1200"
